Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

The embodiment of the utility model provides a pass cutter for stick wire rod, as shown in figure 2, this cutter includes tool bit and cutter body, and tool bit and cutter body link together, and the front end coplane of tool bit and cutter body forms the cutter face, the cutter face for the conical surface and with roll processing surface between be formed with preset contained angle.

The embodiment of the utility model provides a pass cutter for excellent wire rod, tool bit and cutter body coplane place cutter face become the tapering design, can avoid in roll course of working cutter body bottom and roll contact and take place "gnaw the roller" phenomenon, and the surface area that needs the coping in the cutter coping in the later stage obviously reduces, changes in the control of coping cutter pass precision, satisfies excellent wire rod high accuracy material type control. Is easier to grind, and reduces the consumption of the grinding wheel.

In one embodiment, the cutter has the taper, so that some fault points of machining are eliminated, the machining efficiency can be improved by about 30%, the service time of the cutter can be improved by about 40%, the machining cost is effectively reduced by about 35%, and the implementation effect is good.

The embodiment of the utility model provides a pass type cutter for stick wire rod can be through the line cutting machine-shaping, for example, can obtain behind the tool bit through the line cutting mode, connect the tool bit through the welding mode and form the cutter wholly on the cutter body.

Alternatively, the cutter head and the cutter body can be of an integrally formed structure.

As shown in fig. 3, the front end of the tool bit of the hole-type tool for rod and wire provided by the embodiment of the present invention is a three-cutting dumbbell hole type.

The embodiment of the utility model provides an in, be formed with between cutter face and the roll machined surface and predetermine the contained angle in order to avoid gnawing the rail, the numerical value of this predetermine contained angle can be confirmed according to actual production situation and technology demand. Illustratively, the included angle between the tool surface and the roll processing surface may be 5-7 degrees, for example, 5 degrees, 6 degrees, 7 degrees, etc. The included angle between the preferable cutter surface and the roller processing surface in one embodiment of the utility model is 6 degrees.
